Windows 11 update KB5094126 (Build 26200.8655), released on June 9, 2026, has caused boot failures, blue screens, and BitLocker recovery prompts for users, particularly affecting business devices from HP and Dell, including models like HP EliteBook 840 G10 and Dell Precision 7530. The issues stem from changes in Secure Boot and EFI partition modifications, with insufficient EFI partition space leading to errors. A workaround involves disabling Secure Boot in BIOS. Additionally, users have reported disruptions with OneDrive and Microsoft Word integration, particularly in enterprise environments. Microsoft has not yet acknowledged these problems.
